We will simplify the configurations on the
network by setting 3 routers reflectors
that will take and centralize all the BGP
announcements of all backbone routers,
recalculate the best route and then redistribute
the BGP table on all routers.

We should gain in BGP performance and in reliability
on the optic fibre cuts.

VIX works on 193.203.0.0/24 which is a private network.
For an unknow reason VIX announces this network on Internet.
The trafic was redirected. We have filtered the announcements
in order to avoid having 193.203.0.0/24 in the BGP
